computer freezes randomly

Postby enthalpy on Wed Oct 10, 2012 10:21 pm

My computer 'hard' freezes (i.e., the only way to get out is to do a hard reset by hitting the power switch), where the num/cap/scroll locks keys don't even work. This happens randomly when I browse the Internet on Firefox. It doesn't seem to happen when the PCI Express wireless adapter is disconnected. I am using a TP-Link WDN4800 wireless adapter with whatever default driver is already installed on Linux Mint (I did not install any additional drivers). I added the line

Code: Select all
options ath9k nohwcrypt=1


to /etc/modprobe.d/ath9k.conf since (see: http://ubuntuforums.org/showthread.php?t=1970955) I was getting max speeds of 10 KiB/s without that line added.

Frankly, I'm not sure whether it is due to my wireless adapter or some kind of Firefox plug-in causing my computer to freeze... but it is definitely related to Internet access since my computer is stable with the wireless adapter removed without Internet access.

Edit: Edit: Never mind. The syslog actually didn't record anything when the system froze.

I had a similar problem the other day. It was similar by the fact I had a "hard" freeze whilst I was browsing with Firefox. I am not aware of the cause, and would like to find out.
I would like to keep an eye on this, to see if there is any resolution.

Have you tried disabling hardware acceleration on Firefox?
Edit, Preferences, select the Advanced tab and uncheck "Use hardware acceleration when available".

Are you using the latest drivers for your video card? The latest proprietary drivers are usually the best to use.

Have you tried using another browser to see if it's related to your network adapter?

Can you connect to the Internet through other means to see if it still happens?

Did you tested your RAM?
Tap the shift key during boot and select Memory Test (memtest86+)

Is your power supply up to the challenge of powering your computer? Modern video cards do draw a lot of power. Please note many generic PSU's aren't capable of delivering their rated wattage.

You said usually, when else does it happen?

Oops...forgot to edit my post. It actually happens even when I'm not browsing Firefox. As long as the wireless adapter is plugged into its PCI-express slot, my computer randomly crashes. I checked the memory, power supply, and everything and everything seems to be fine. I am using integrated graphics on my i5 so graphics should not be an issue. I spent too much time trying to solve the issue so I gave up and went back to Ubuntu (with cinnamon) and everything is fine again.

I am still unsure what the problem is though but I am posting an update just in case it might help somebody else...

I believe this is exactly the same problem that I am having

Unfortunately nobody seems to have found a solution. But I hope this comes to the attention of the Mint team that this is a very real issue.

I was having a similar problem and seemed to have fixed it.

I installed this newer kernel and it completely fixed my problems:

What computer are you using?

Hi,
I've installed the new Kernel as you suggested it ans that simply went worse. The boot is slower, i've lost all the wireless settings and other things. How do i get back to the Kernel previously used? and does anyone have other suggestions to solve the freezing issue?
Thanks
